3. Case sensitivity - not all filenames are treated the same way

If you develop on Windows or OSX, and your code includes a file or reference to a file like jQuery/jquery.js — the Netlify build may fail due to the mixed case filename. The file system used in Netlify builds is case sensitive, while your build environment is not. Unfortunately, the error messages that result may not clearly indicate this!

It can be challenging to effectively change case of a file stored in Git from your case insensitive local environment. This article on StackOverflow describes a good workflow, as simply renaming and committing will almost certainly not have the desired effect.
